Game mode: Experimental

Experimental mode was added to the agar.io game on June 11, 2015. As the name suggests, it’s a game mode where the developer can test out new features and mechanics. If you play on the experimental game mode, you may encounter some new, and possibly weird, mechanics.

Based on feedback, the developer may implement new experimental mechanics or remove them, or even create a separate game mode using those experimental mechanics. As agar.io progresses, new mechanics and general improvements will be made to the game. Experimental mode is a great way for that to happen.

In its place, a new mechanic has been added, where there are “spawners” that passively spawn food. Any cell that enters the spawner will be shredded into food. Here’s what that looks like:
